Not the one? For a standard bowl with an ordinary round outlet, the MP100 moves more water per stroke. Sinks and tubs need a different mouth, so look at the Shorty or the MP200.
Many low-flush bowls have an oval or narrow outlet, and a flat cup can't seal on that shape. The MP1600's extended funnel nose bends 90 degrees and goes into the outlet. That way the 8 cups from the bellows go down the pipe instead of around the sides.
It works differently from a cup plunger. You let the bellows fill with water first, then start with slow strokes and build up speed, which keeps the spray down. Owners who fought odd-shaped bowls say it cleared clogs their regular plungers couldn't touch, some within a few strokes.

Maker's claims
Designed for low-flush, 1.6-gallon toilets
Extended funnel nose bends 90 degrees into the outlet of standard and elongated bowls
8 cups of water displacement
Air relief valve against overflow
Several owners got sprayed on the first try by pushing hard before the bellows held water. Another found the hard plastic nose didn't seal on their toilet, and one said heavy use wore out the folds after about a year. Rinse it well after each job, since waste collects in the funnel and the folds.
Clogged toilet: the short version
Stop the water
Don't flush again. If the bowl is near the rim, close the shutoff valve behind the toilet.
Protect the floor
Lay old towels around the base and put on rubber gloves. Keep a bucket close for bailing.
Set the water level
You want water over the plunger's nose and room below the rim. Bail some out if the bowl is full, or pour some in from a jug if it's low.
Seat the nose and let the air out
Put the nose into the outlet at the bottom of the bowl. Press down slowly the first time, so the air leaves through the valve instead of lifting water over the rim.
Work the strokes
Pull up to fill the bellows, then push down firmly. Keep a steady rhythm for 15 to 20 strokes without breaking the seal.

It's a plunger, but not in the way you may think.
This plunger does a great job in relieving clogs in a low flow toilet but beware that is needs to suck up water into the plunger first so you can agitate the clog. It fits well into the large opening though you may have to nudge it in past the opening you see and into where it narrows deeper in the drain. Start slow and increase velocity so you don't spray. DO NOT try to use this plunger like you would with traditional plungers unless you want a brown shower!

Best Plunger
I live in an old house with old plumbing. I need a plunger fairly frequently. The old-style just didn’t do the trick. This one gets down into the opening of the waste drain and has much stronger pressure flow for each push. I have them in each bathroom. So glad they come with their own storage buckets. They might be prettier in a color other than black, but their effectiveness far outweighs that minor aesthetic issue.

Sadly did not work with my Kohler toilet.
Just didn’t work on a paper clog in my stupid low flow toilet so had to call plumber. It seems sturdy and well made however.

Worked great!!
This plunger is made for low flush toilets. Read directions to OPEN it and then CLOSE before using and it does the trick right away. Regular plungers didn't work on my toilet, but this funnel nose one fit perfectly and cleared the blockage on the first try.

Doesn't work
Did not seal like it said it would. Toilet was plugged up, so I had to put the plunger in with the feces. Plunger of course sucked up the feces, and churned them up. Feces got all over the inside and outside of the plunger. If I thought about it before purchasing, I would have realized it there is no way this plunger would work, and if it did work it would create a nasty mess
